Thank you again for quick replies! I just measured my inland pla I bought as a starter roll and sure enough it is averaging like 1.69 or 68. Please forgive my ignorance but as far as the cube calibration goes should I print one and then measure with calipers? Use it to see if my rates are correct? I was under the understanding that the firmware on this printer is not adjustable so would I be able to change the extruder steps/mm or would I be doing it just to adjust my extrusion multiplier? I've done a couple benchys which printed totally fine minus a little stringing as mentioned but when I tried the makerbot octopus waving it did not fill in the top layers which was why I began adjusting the extrusion multiplier. Thank you again for help.
